Wireless position detection blood pressure continuous measurement system

The present invention relates to a blood pressure measurement system, and more particularly to a wireless body position detection blood pressure continuous measurement system.

In recent years, with the changes in life pace and diet patterns, the incidence of cardiovascular diseases directly related to or closely related to blood pressure has risen sharply in the major national disease statistics. Therefore, blood pressure is measured regularly and effectively as personal health management. Self-testing is increasingly urgent and important.

However, at present, one of the main blood pressure measuring devices adopts the cuff measurement method, which has many inconveniences in practical use, and is also prone to misjudgment such as sampling errors in measurement interpretation. situation. For example, a blood pressure measuring device using a cuff can only be applied to a short-time measurement, and the user cannot perform continuous blood pressure measurement for a long time, and the user also needs to measure for a fixed period of time. In order to avoid the congenital difference in the blood pressure values of the human body in each section of the morning and evening, causing interference in the interpretation of the measured values, and even making a false positive.

In addition, the traditional blood pressure measuring device, the accuracy of the measured data, in addition to the sitting posture and the hand placement relative to the user's measurement Whether the location is appropriate or not, the current emotional state of the user also influences the results of the measurement data. Therefore, when using a conventional cuff blood pressure measuring device, the user needs 5 to 10 minutes of rest preparation time to relax the whole body in order to obtain an actual and accurate blood pressure measurement value. Furthermore, the conventional cuff pressure blood pressure measuring device, during the measurement, will be compressed by the compression zone, which is likely to cause discomfort to the user.

Therefore, there is an urgent need to develop a novel wireless position detection blood pressure continuous measurement system, thereby providing a measurement mechanism that is more convenient for the user to operate, and can continuously measure the blood pressure value for a long time, and can effectively eliminate the miscellaneous Interference value.

Before the present invention is described in detail in the present embodiment, it is to be noted that in the following description, similar elements will be denoted by the same reference numerals. Again The drawings are intended to be illustrative only and not necessarily to scale.

Please refer to FIG. 1A and FIG. 1B , which are respectively a functional block diagram and an actual use configuration diagram of a wireless body position detection blood pressure continuous measurement system according to an embodiment of the present invention. As shown, a wireless body position detection blood pressure continuous measurement system 100 includes an electrocardiography (ECG) device 110, a photoplethysmographic (PPG) device 120, and an algorithm processor 130.

Specifically, the electrocardiograph device 110 is disposed in the first measured portion 210 of the user 200 for measuring the electrocardiogram signal of the user 200, and the electrocardiograph device 110 can include the first motion sensing module 112 and the first A wireless transmission module 114. The first motion sensing module 112 is configured to sense the first motion signal of the first measured portion 210 of the user 200, and the first wireless transmission module 114 is configured to wirelessly transmit the ECG signal and the user. Position signal, for example: the first action signal.

Furthermore, in one embodiment of the present invention, the electrocardiograph device 110 can include a sensing electrode unit, such as an inductive electrode sheet, having a re-stickable function for adhering to the chest of the user 200. Before, the ECG signal of the user 200 is directly measured. In addition, the first motion sensing module 112 can simultaneously sense the first motion signal corresponding to the operating frequency and intensity of the chest and the upper body of the user 200. Then, the first wireless transmission module 114 wirelessly transmits the corresponding measured electrocardiogram signal and the first motion signal to the algorithm processor 130.

On the other hand, the photoplethysmography device 120 is disposed in the second portion 220 of the user 200 for measuring the photoplethysmographic signal of the user 200, and the photoplethysmography device 120 can include a second sense of motion. The module 122 and the second wireless transmission module 124 are tested. The second motion sensing module 122 is configured to sense the second motion signal of the second measured portion 220 of the user 200, and the second wireless transmission module 124 is configured to wirelessly transmit the optical volumetric signal and The second action signal. More specifically, in an embodiment of the present invention, the optical plethysmography device 120 can include a light emitting device and a light receiving device, and are spaced apart from each other in the body of the photoplethysmography device 120, wherein the light emitting device An optical signal is generated to contact the skin of the user, and the light receiving device corresponds to the light signal received from the skin of the user contact surface, thereby capturing the amount of different light refracted by the user's blood flow, thereby knowing the blood flow rate and the heart. Electricity and other signal information.

However, as shown in FIG. 1B of the present case, the photoplethysmography device 120 can be a wearable device, such as a wristwatch, that is directly attached to the wrist portion of the user 200 to measure the light plethysmographic signal of the user. In this way, the second motion sensing module 122 can simultaneously sense the second motion signal corresponding to the operating frequency and intensity of the user's 200 hand and its arm as a whole. In addition, the present invention is not limited thereto, and the optical plethysmography device 120 can be worn on other limb positions of the user according to actual use requirements. Then, the second wireless transmission module 124 wirelessly transmits the ECG signal and the second motion signal measured by the second motion sensing module 122 to the algorithm processor 130.

Thereby, the algorithm processor 130 will be able to transmit from the first wireless The transmission module 114 and the second wireless transmission module 124 synchronously receive the ECG signal and the first motion signal respectively measured from the first measured portion 210 (for example, the user's chest), and the second measured signal. A portion 220 (for example, a user's hand) measures the photoplethysmographic signal and the second motion signal to acquire a pulse transit time (PTT), and then calculates a blood pressure information. More specifically, the algorithm processor 130 obtains the pulse transit time by the time difference between the received electrocardiogram signal and the photoplethysmographic signal, thereby generating blood pressure information.

In addition, in an embodiment of the present invention, the algorithm processor 130 can be a smart mobile device or a cloud server, thereby establishing a wireless signal transmission mechanism to avoid greatly affecting the user due to the physical transmission line. activity. Furthermore, if the wireless connection is used for electrical connection, the wireless transmission module of the present invention may be an infrared communication module, a radio frequency communication module, a Bluetooth communication module, a WIFI module, a group bee communication module, and a third. Generation, fourth generation, fifth generation mobile communication module or other equivalent wireless transmission module.

Continuing to refer to FIG. 1A, the algorithm processor 130 may further include a blood pressure algorithm processing module 132 for filtering noise of the electrocardiogram signal and the optical plethysmographic signal, and the band signal according to the preset non-reference value. The algorithm processor 130 generates blood pressure information by filtering the electrocardiogram signal and the photoplethysmographic signal.

More specifically, when the action intensity or the action frequency of one of the first action signal and the second action signal is greater than a predetermined upper limit value or a programmable upper limit value, the blood pressure algorithm processing module 132 filters out Corresponding to the ECG signal and photoplethysmographic signal. For example, The blood pressure in the dynamic state is actually lower in reference value. Therefore, when the user is exercising, the blood pressure measurement of the motion signal will be excluded because the action intensity or the action frequency of the motion signal will be greater than the preset upper limit value.

In another embodiment, when the heart rate represented by the electrocardiogram signal is higher than the preset upper limit value or the programmable upper limit value, the blood pressure algorithm processing module 132 filters out the corresponding electrocardiogram signal and the optical plethysmography signal. For example, if the state of excitement, tension, or other conditions that cause the heartbeat to be higher than normal, the blood pressure actually has a lower reference value, so when the user is in this state, the heart rate is higher than the preset upper limit. Therefore, the blood pressure measurement during this period will also be excluded.

However, the preset parameters referred to in the above embodiments refer to parameter values that the user can input in advance, and the programmable parameters are parameters that the user can input dynamically according to the actual demand during the training operation; For example, since the blood pressure value of the human body is different at each time of the morning and evening, and is also closely related to the current activities of the activity, in addition to the user before inputting the measurement, the preset parameters are input in advance to exclude or separate. In addition to the blood pressure measurement data generated by the high heart rate or the intensity of the exercise and the high frequency, the user can also input the immediate input mode, such as day mode and sleep mode, depending on the measurement period or the activity. Or programmable parameters such as exercise mode to increase or decrease the upper threshold value of the heart rate, action intensity and frequency used to exclude the recorded blood pressure measurement, so as to record the reference value more positively and properly. Blood pressure data. In this way, the blood pressure algorithm processing module 132 can effectively according to the preset upper limit value or the programmable upper limit value, and eliminate the corresponding measurement due to excessive user action or emotional fluctuation. Raw non-target measurements.

Next, please refer to FIG. 2 , which is a functional block diagram of a wireless body position detection blood pressure continuous measurement system according to another embodiment of the present invention. As shown, the algorithm processor 130 can further include a storage module 134 and a marking module 136. The storage module 134 is used to record and store blood pressure information. The marker module 136 can be used to mark blood pressure information based on a preset upper limit value or a programmable upper limit value. Thereby, the measurement system 100 can effectively distinguish and summarize the blood pressure information, so as to provide the user 200 to further explore the blood pressure information of each section, which can be used as a basis for self-health detection.

Further, the main difference between the embodiment and the foregoing embodiment is that, in this embodiment, when the action intensity or the action frequency of the action signal is greater than a preset upper limit, or the heart rate is higher than the upper limit of the heart rate, The marking module 136 gives the corresponding electrocardiogram signal and the photoplethysmographic signal to a calibration mark, that is, the blood pressure measurement result with no reference value is specifically indicated for reference by the user. Alternatively, the marking module 136 can directly delete the segmentation result directly, in addition to specifically indicating the segment result. Of course, the task of deleting the measurement result is not limited to the execution of the tag module 136, and may be performed by the algorithm processor 130 or the blood pressure algorithm processing module 132.

Furthermore, in another implementation of the present invention, the storage module 134 can record the required measurement value according to the heart rate and the amount of body position change of the user. For example, please refer to FIG. 3 , which illustrates a record storage flowchart of measurement information according to another embodiment of the present invention.

As shown in the figure, first, the activation of the heart is started in step S300. The electrogram device 110 and the photoplethysmography device 120 measure the physiological signals of the user 200. Next, in step S301, the read light plethysmographic signal and the electrocardiogram signal are received, and the pulse wave transit time is calculated to obtain the instantaneous blood pressure information such as the heart rate of the user. Furthermore, in step S302 and step S303, the current heart rate of the user can be compared with the preset upper limit value and the preset lower limit value respectively, wherein when the user's heart rate is greater than the preset upper limit value and When it is less than the preset lower limit, the physiological information measured by the user is excluded.

Next, in steps S304 and S305, the amount of change in the position of the user can be further considered. Further, step S304 and step S305 are based on the user's first motion signal and the second motion signal, and sequentially analyze whether the user's body position swing angle and the action frequency meet a limit range condition, wherein When one of the posture change angles and the action frequency does not meet the limit condition, the physiological information measured by the user is also excluded. For example, step S304 is to determine whether the swing tilt angle of the user's body is in compliance with the limit range condition; then, step S305 is to determine whether the swing amplitude and frequency of the user's limb portion are also in compliance with the limit range condition. In this way, after the state of the heartbeat rate and the abnormal change of the body position during the measurement period of the user is excluded through steps S302 to S305, the physiological measurement value of the user in the normal state can be appropriately recorded and stored in step S306. It corresponds to the blood pressure information obtained by the operation.

Referring to FIG. 4, the optical plethysmography device 120 can include a display interface unit 126 for displaying the photometric plethysmographic signal. However, the present invention is not limited thereto, and in other embodiments, The electrocardiograph device 110 can also include a corresponding display interface unit for displaying the measured ECG signal in real time according to actual application requirements.
